I looked at the course outline for each one and they are roughly similar.
I also own the Eclipse Rich Client Platfrom (2nd edition) book. Can you recommend other resources to enhance my RCP knowledge?
Thank you.

I ended up taking the RCP Quickstart class online by Modular Mind and it more than met my expectations: Patrick (the instructor) covered the topics very thoroughly and I particularly liked the format of the class.

This online class lacks nothing in comparison to on-site training classes because the size of the class is small, the notes for the class are exceptional and you can ask any question at any time.
I was very happy with Patrick's passion and level of expertise not only in Eclipse plugin development and RCP but also in the maven-based build "tycho" which my team uses. I highly recommend this class to anyone who wants to learn RCP in a very fast and effective way.
